Information contained in the "file.ffgnn" files supplements the basic wire
frame model "file.poly" by specifying the half-conics, lines and boundaries
visible from specific directions. This set of features is referred to as a cliche.
Both files must be loaded via the Smm Matcher Tool.

The standard camera calibration data structure contains transformation parameters
which specify the location of the optical centre of the camera in the co-ordinate
system of the calibration reference. When applied to object model the transformation
therefore corresponds to that which will project the model into the image.
Model based calibration can be initialised in one of two ways. Firstly the
wire-frame object can be manipulated in the Model Tv associated with the
wire-frame model matcher until the view approximates the orientation of the object
in the left image. Secondly, an estimate of the transformation is available following
a successful model matching with the Model Tool.

The resulting transformations for both cameras
can be visualised by setting the Model Parameters, Project option to "all/print" and
using the "model proj" function. This will project all features in the absence of
specified view cliches. Use of the "cliche" option will project the features from
the closest available cliche to the direction to the transformation. Points passing
hypothesis tests are coloured green, those failing are blue.
